The belt keeps coming off of the motor shaft for roller bar
Your belt is either stretched or the wrong size or the brush bushings are worn and allowing the brush to wobble or the motor is loose in its housing. You need to check all.
Rotate the brush and try to wobble it from the pulley end.
Flip the belt inside out, it if appears cupped, cracked or shiney and slips easily on and off the brush it is stretched. Generally this unit needs anew belt evrey 6 months, broken or not, they get hot and stretch. Do not buy a new belt by matching size, a worn belt can be 20-30% oversized and not broken but totally useless.
The motor shaft should be cleaned with W/D 600 grit sand paper. Motor should have no wobble in the shaft
